Unique Properties & Equilibrium Effect of NaDCC

NaDCC dissolves in water to release HOCl - measured as available chlorine

Only 50% of the “total” available chlorine is actually present as “free” available chlorine

The remainder is “combined” in the form of mono – or dichloroisocyanurate

The ratio of “free” and “combined” available chlorine always remains at 50:50

As “free available” chlorine is used up (e.g. organic matter, microorganisms etc.) the balance is disturbed

Part of the “combined” available chlorine is then “freed” to restore the 50:50 ratio

At the same solution strength (125mg/l) the NaDCC is twice as effective as the NaOCl, and at half the solution strength, (62.5mg/l), it still retained a similar capacity.

​Kinder to Users and Surfaces than Bleach

NaDCC is less damaging to users, surfaces, clothing and equipment

HMIS health rating of 1 – compared to health rating of 2-3 for bleach

Similar pH to skin – will not burn the skin

Will not harm floor finishes

​HMIS health rating of 1 reduces risk/facilitates worker safety

​More stable, longer shelf life than Bleach

Longer shelf life in solution than bleach – 1 week compared to 1 day for bleach

Longer shelf life before dilution than bleach – 5 years compared to 12 months for bleach

Continues working in the presence of organic load (i.e. blood and dirt)

Residual killing power – unlike bleach, it goes on killing until dry

NaDCC (sodium troclosene) retains killing power due to a 50 / 50 chemical equilibrium that continues to generate chlorine to replace that which is being used up in the process of destroying micro-organisms or contact with organic loads. This means that it is not inactivated by dirt/cloths/organic matter as occurs with bleach.

Lasts longer, goes further, less waste

​Simpler to use than Bleach

Exact dosage every time delivers accurate strength solution

Eliminates “measure and pour” guesswork

No dispensing equipment required

​Less odor, nicer environment for all

​Smells Better than Bleach

​Mild swimming pool-like odor

Less irritating to workers

Less irritating to staff, visitors, room occupants

Proven Track record in reducing C.Diff. rates

By comparing C. diff rates in UK hospitals (where NaDCC is used) and US hospitals (where bleach is used), we can see their relative effectiveness.

Starting in 2008 UK hospitals began switching from bleach to NaDCC, due to COSHH regulations. This change to NaDCC was based on Health and Safety requirements.By the end of 2010, the changeover was complete. Today 100% of UK and Irish hospitals use NaDCC. The graph below shows the impact of the change in C. diff rates in UK hospitals and how those hospitals compare to US hospitals (which still use bleach). First paper published demonstrating reduced rates of C. diff infection in 2003*.
